System and Method to Change SVS Mode

Abstract

A system may include a display and a processor. The processor may: output a synthetic vision system (SVS) taxi mode exocentric view of an aircraft while the aircraft is performing taxi operations and when the aircraft is not in a predetermined exclusion zone, the predetermined exclusion zone including portions of a runway where the aircraft is able to begin taking off, wherein a width of the predetermined exclusion zone is based at least in part on at least one of a width of the runway or a classification of the runway; and output an SVS flight mode egocentric view from the aircraft when the aircraft is in the predetermined exclusion zone. The display may display the SVS taxi mode exocentric view until the aircraft is in the predetermined exclusion zone and display the SVS flight mode egocentric view when the aircraft is in the predetermined exclusion zone.

What is claimed is: 
     
         1 . A system, comprising:
 at least one display; and   at least one processor communicatively coupled to the display, the at least one processor configured to:
 output, to the at least one display, a synthetic vision system (SVS) taxi mode exocentric view of an aircraft while the aircraft is performing taxi operations, while the aircraft is on ground, and when the aircraft is not in a predetermined exclusion zone, the predetermined exclusion zone including portions of a runway where the aircraft is able to begin taking off, wherein a width of the predetermined exclusion zone is based at least in part on at least one of a width of the runway or a classification of the runway; and 
 output, to the at least one display, an SVS flight mode egocentric view from the aircraft when the aircraft is in the predetermined exclusion zone, 
   wherein the at least one display is configured to display the SVS taxi mode exocentric view until the aircraft is in the predetermined exclusion zone and to display the SVS flight mode egocentric view when the aircraft is in the predetermined exclusion zone.   
     
     
         2 . The system of  claim 1 , wherein the width of the predetermined exclusion zone is based at least in part on the width of the runway. 
     
     
         3 . The system of  claim 1 , wherein the width of the predetermined exclusion zone is based at least in part on the classification of the runway. 
     
     
         4 . The system of  claim 1 , wherein the width of the predetermined exclusion zone is further based at least in part on dimensions of the aircraft. 
     
     
         5 . The system of  claim 1 , wherein the SVS taxi mode exocentric view has an eye point above and behind the aircraft. 
     
     
         6 . The system of  claim 5 , wherein the SVS taxi mode exocentric view includes a depiction of the aircraft. 
     
     
         7 . The system of  claim 1 , wherein the SVS flight mode egocentric view includes primary flight display symbology. 
     
     
         8 . The system of  claim 7 , wherein the SVS taxi mode exocentric view has less of the primary flight display symbology than the SVS flight mode egocentric view. 
     
     
         9 . The system of  claim 1 , wherein a pilot of the aircraft is able to make an auto or off selection for a SVS taxi mode, wherein the auto selection of the SVS taxi mode enables the at least one processor to automatically transition between the SVS taxi mode exocentric view and the SVS flight mode egocentric view, wherein the off selection of the SVS taxi mode enables the at least one processor to only output the SVS flight mode egocentric view. 
     
     
         10 . The system of  claim 1 , wherein the at least one processor comprises: at least one primary flight display (PFD) processor configured to execute a PFD application, at least one SVS processor configured to execute an SVS application, at least one flight management system (FMS) processor configured to execute an FMS application, and at least one other processor configured to execute an application. 
     
     
         11 . The system of  claim 10 , wherein the at least one PFD processor is further configured to: receive sensor data from sensors; receive an auto or off selection for a SVS taxi mode; receive a location including a width of the predetermined exclusion zone from the at least one other processor; output a scene selection to the at least one SVS processor instructing the SVS processor to generate the SVS taxi mode exocentric view or the SVS flight mode egocentric view; and receive the SVS taxi mode exocentric view or the SVS flight mode egocentric view from the at least one SVS processor. 
     
     
         12 . The system of  claim 11 , wherein the at least one SVS processor is further configured to: receive sensor data from the sensors; receive the scene selection from the at least one PFD processor; output the SVS taxi mode exocentric view or the SVS flight mode egocentric view to the at least one PFD processor; and output a runway database to the at least one other processor. 
     
     
         13 . The system of  claim 12 , wherein the at least one FMS processor is further configured to: receive sensor data from the sensors; and output departure runway information to the at least one other processor. 
     
     
         14 . The system of  claim 13 , wherein the at least one other processor is further configured to: receive the runway database from the at least one SVS processor; receive the departure runway information from the at least one FMS processor; receive information of dimensions of the aircraft; determine an exclusion zone resulting in the predetermined exclusion zone; and output the location including the width of the predetermined exclusion zone to the at least one PFD processor. 
     
     
         15 . A method, comprising:
 outputting, to at least one display, a synthetic vision system (SVS) taxi mode exocentric view of an aircraft while the aircraft is performing taxi operations, while the aircraft is on ground, and when the aircraft is not in a predetermined exclusion zone, the predetermined exclusion zone including portions of a runway where the aircraft is able to begin taking off, wherein a width of the predetermined exclusion zone is based at least in part on at least one of a width of the runway or a classification of the runway;   outputting, to the at least one display, an SVS flight mode egocentric view from the aircraft when the aircraft is in the predetermined exclusion zone;   displaying the SVS taxi mode exocentric view until the aircraft is in the predetermined exclusion zone; and   displaying the SVS flight mode egocentric view when the aircraft is in the predetermined exclusion zone.
